Washington Monument State Park
Washington Monument State Park is dog-friendly. You and Fido can hop on a section of the Appalachian Trail to get to the centerpiece of the park, Washington Monument, the first completed monument in George Washington's memory. Located on top of South Mountain, the views from the top are incredible, especially during the fall season. Dogs are welcome to join their owners on a leash under six feet, as long as owners clean up any mess after them. Washington Monument State Park is open 8am until sunset from April to October and 10am until sunset from November to March. Visit Website
